Schwartz's has never served fried chicken! The menu is minimalist - smoked meat, steak, grilled liver and, I think, some kind of sausage. They sell smoked chicken and turkey but only for takeout. The sign says "Order early for the holidays" and they never take it down, because somebody's holidays are bound to be on the way at any time.
The menu may be typically kosher but, as I understand it, it's not regarded as an officially kosher institution any more. In fact, I'm pretty sure the current owner is Greek.
You can't get alcohol at Schwartz's. I once came in to hear one of those weary, elderly waiters saying to a fancily-dressed female customer: "Lady, you want wine, we have cherry cola. You want beer, we have ginger ale. We don't have a license. This is Schwartz's."
